In practical applications, obstacle is closer apart from antenna for base station, influenced caused by blocking it is bigger, and user terminal away from
Closer from antenna for base station, user more concentrates.Therefore, in one embodiment, according to MR.TadvRsrp sampling number data acquisitions
The sampling in different Reference Signal Received Power section in MR.Tadv.00 (apart from 0~234.72m of antenna, i.e. antenna near point region)
It counts and is ranked up, (N is greater than the positive integer equal to 2, for example, 4), being denoted as to obtain top n sampling number
{NumTop1, NumTop2..., NumTopN}。
In a step 102, the ratio of the sum of each sampling number and multiple sampling numbers is determined according to multiple sampling numbers,
And determine the first variance of the ratio of multiple sampling numbers.
In one embodiment, top n sampling number is normalized, i.e., by N number of sampling number respectively with it is N number of
The sum of sampling number (that is,) be divided by obtain the sum of each sampling number and N number of sampling number ratio (that is,
{RateTop1, RateTop2..., RateTopN,).The of the ratio is calculated according to following equation 1
One variance.
Wherein,
First variance can reflect the signal strength section distribution centrality in the near point region.Fig. 6 is shown according to this
The schematic diagram of the signal strength section distribution centrality of the embodiment of invention and the ratio of each sampling number.As shown in fig. 6, concentrating
Property with sampling number value reduction and by the ratio of the sampling number influenced reduce.In practical applications, centrality is got over
Height, wireless environment is more single, otherwise wireless environment is more complicated.
In step 103, sampling number subset is selected from multiple sampling numbers according to first variance, and determines and adopts
The second variance of the corresponding Reference Signal Received Power of each sampling number in number of samples subset.
In one embodiment, Reference Signal Received Power can be the maximum ginseng in corresponding Reference Signal Received Power section

One of.For example, the Reference Signal Received Power in the sections MR.RSRP.10 can be -60dBm, -65dBm or -62.5dBm.
In one embodiment, the subset of top n sampling number is calculated (for example, M sampled point according to following equation 2
Number) in the corresponding Reference Signal Received Power { Rsrp of each sampling numberTop1, RsrpTop2..., RsrpTopM(wherein, M is big
In equal to 2 and less than or equal to N positive integer) second variance.
Wherein
Wherein, according to the above-mentioned centrality Rate being calculatedconcentricityTo determine the M values in formula 2.Fig. 7 shows
The sampling of the distribution of signal strength section centrality, second variance and sampling number subset according to an embodiment of the invention is gone out

Determine whether antenna for base station is seriously stopped.In one embodiment, can be based on multiple average reference signals receive power with
Corresponding first blocking severity threshold relatively determines whether antenna for base station is seriously stopped, wherein the first blocking severity threshold
Threshold value is verified less than corresponding power.For example, in one embodiment, working as Rsrpdistance50mLess than or equal to -100dBm and
Rsrpdistance100mWhen less than or equal to -115dBm, it may be determined that antenna for base station is seriously stopped.
In one embodiment, can be based on the corresponding Reference Signal Received Power of multiple sampling numbers respectively with accordingly

Number receive power interval sampling number and for base station cell be less than weak coverage power threshold value reference signal reception work(
Total sampling number in rate section；Determine that near point region is less than the sampling in the Reference Signal Received Power section of weak coverage power threshold value
Points and the of total sampling number in the Reference Signal Received Power section less than weak coverage power threshold value for base station cell
Two ratios；And the comparison of severity threshold is stopped to determine whether antenna for base station is seriously hindered with third according to the second ratio
Gear.For example, according to MR.TadvRsrp sampling number data, obtains MR.Tadv00 (that is, near point region) and be less than weak coverage power
The sampling number of threshold value (for example, -115dBm) and all MR.TadvXX in the base station cell are less than weak coverage power threshold value (example
Such as, -115dBm) total sampling number the second ratio, when second ratio be more than third blocking severity threshold (for example,
60%) when, it may be determined that antenna for base station is seriously stopped.Second ratio more high impedance is more serious, on the contrary then stop slighter.
In step 807, according in multiple sampling numbers maximum sampling number with time big sampling number is corresponding refers to
The comparison of difference between signal reception power and object-attenuation loss table determines the type of obstacle.Fig. 9 shows object
Body-attenuation loss table.As shown in figure 9, construction material has respective attenuation loss.For example, when maximum sampling number with it is time big
When difference between the corresponding Reference Signal Received Power of sampling number is 13~18dB, obstacle is determined to be concrete walls.
In step 808, the blocking type of antenna for base station is determined.It in one example, can be from LTE-MR data acquisitions
Total sampling number in all Reference Signal Received Power sections near point region, and determine that near point region is less than weak coverage power threshold
The sampling number in the Reference Signal Received Power section of value is always adopted with all Reference Signal Received Power sections near point region
The third ratio of number of samples；It is distributed the height of centrality, the according to the signal strength section in the near point region of first variance instruction
Two ratios, third ratio determine blocking type.Figure 10 shows centrality, the second ratio, third ratio and blocking type
Relationship.For example, centrality is high, the second ratio is high, third ratio is high, then mean to stop that type is that proximal end barrier is more serious.
